ABSTRACT:
Even for a driving impedance of 25 Ω, high transmission waveform quality of an optical transmission module is maintained using an optical modulator element designed for a driving impedance of 50 Ω. The above can be achieved by adopting an optical module100that includes an input electrode for electrical signals, an optical modulator element for modulating laser light using the electrical signals, a termination resistance element, a first bonding wire for connecting the input electrode and the optical modulator element, a second bonding wire for connecting the optical modulator element and the termination resistance element, and a third bonding wire for connecting the input electrode and the termination resistance element.
